2026-03-13

Performance

Fixes

• Search: Fix image index misalignment in multimodal embedding pipeline
• Search: Fix provider race conditions and concurrent local model loading in parallel embedding

• Search: Add image match badge to search results, distinguishing text and image hits

Performance

2026-03-05

New Features

• History: Agent mode and slides narration storage sizes now display in the history list (legacy records backfilled on startup)

Improvements

• History: Move delete button to absolute-positioned overlay so the content area is no longer compressed, improving visual symmetry when not hovered

v0.31.5

2026-03-05

New Features

• Lightbox: Add generation info panel (ℹ️ button or I key) showing model, resolution, ratio, temperature, and other generation parameters, with drag and resize support
• History: Display model name tag in history list between status badge and file size

Refactor

• Lightbox: Extract drag/resize logic into useDraggablePanel composable, shared by transcript and info panels

v0.31.4

v0.31.3

2026-03-04

Security

• Dependencies: Fix serialize-javascript RCE vulnerability (GHSA-5c6j-r48x-rmvq) via overrides to 7.0.4

Improvements

• Dependencies: Upgrade 14 packages — Vue 3.5.29, Tailwind CSS 4.2.1, Fabric 7.2.0, ONNX Runtime Web 1.24.2, pdfjs-dist 5.5.207, Three.js 0.183.2, Plotly 3.4.0, and more

v0.31.2

2026-03-04

Improvements

• Slides: Page list height now adapts to viewport size, significantly increasing usable space on desktop

Performance

• Slides: Parallelize storage writes (OPFS + IndexedDB) after regeneration confirmation, and show success toast only after save completes
• Slides: Parallelize image and narration OPFS storage on initial generation, eliminating duplicate loadHistory calls, with a new "saved to history" confirmation toast
• Slides: Fix audio player appearing tens of seconds late by setting preview URLs before blocking OPFS image storage

v0.31.1

2026-03-03

New Features

• Mobile Debugging: Add Eruda mobile console via ?debug query param, lazy-loaded to avoid impacting normal performance

Fixes

• OCR: Fix WebGPU OCR failure (Buffer used in submit while destroyed error) caused by a buffer management regression in ONNX Runtime 1.24.1 asyncify WASM (onnxruntime#27068) — upgrade WebGPU WASM CDN to 1.24.2
• Slides: Fix snapshot/dirty fields not being stripped from localStorage sanitizer on restore

v0.31.0

2026-02-28

New Features

• Slide Page Editing: Add inline editing on page cards — edit a single page's content directly without scrolling back to the full textarea. Changes automatically sync back to the textarea (bidirectional binding)
• Change Detection: Each page now tracks content, style, and narration changes via snapshot comparison (not boolean flags), so reverting a change won't falsely mark the page as modified
• Selective Regeneration: New "Generate Modified Pages" button shows a detailed breakdown (e.g., "slides p.2, 5, audio p.3"), no need to regenerate everything
• Page Image Lightbox: Click page card thumbnails to open a full lightbox viewer, with narration audio playback and transcript panel support
• Enhanced History Restore: Loading slides from history now fully restores OPFS images and narration audio, enabling subsequent selective regeneration

Fixes

• Model Selection: Fix regeneratePageWithAudio not using user-selected image model, falling back to default model instead
• History Restore: Fix narration script page IDs not matching actual pages after restore
• History Restore: Fix stale dirty flags persisting through localStorage restore
